The methods heretofore known for constructing vertical gasification chambers with truncated interior angles and varying in cross section in the vertical direction of the chambers have required, relatively to the height of the chambers, a disproportionately large number of brick shapes. Attempts have therefore been made to diminish the number of brick shapes by taking up the differences in dimensions between the different courses by the use of special equalizing bricks or special corner bricks. In applying these methods it is necessary either to make a spe cial equalizing brick for each course, or to use corner bricks the length of whose legs must either be determined beforehand for each course or be obtained by trimming on the job.

All these methods have been effective, in diminishing the number of brick shapes necessary for the construction of gasification chambers with tapered walls, only to the extent that they allow the difference in length of the bounding walls from course to course to be taken up by a single type of brick shape, e. g. by the equalizing brick or by the corner brick. The number of such shapes necessary still depends on the height of the chambers, that is, on the number of courses. 1 But these methods have the further and chief disadvantage that cven with the large number of necessary brick shapes, only such cross sections can be built as have for their dimensions multiplesof those of the stand- 'ard wall brick shape. It has therefore been impossible with the methodsheretofore available'to build out of wall and corner brick shapes taken from stock, tapered walled gasichamber, and so shaped that they at the same time form the truncated corners of the chamber, while the other end of the longitudinal wall of the gasification chamber runs freely into a chase left in the front wall masonry. The truncated corners at this end of the chamber are formed by corresponding bricks of the front wall, made up as brick shapes or trimmed from standard brick on the job. The longitudinal walls of the chamber are then built as heating walls, outof wall shapes which are of one and the same size for the whole job; these bricks are tongued ahd grooved, as are also the parts of the corner brick which go into the longitudinal wall. The space left in the end walls of the chamber, between the legs of the corner shapes and also between the bricks forming the truncated corners at the opposite end, is filled up by the front wall masonry, which is made ofbrick of standard form. It is thus advantageous to have the courses of corner and wall brick the same in depth with those of the ordinary masonry,

I11 order to obtain good bondingof the longitudinal walls, as well as to secure the necessary stability of the chamber by bond.- ing the longitudinal walls into the end walls, the corner brick shapes in alternatecourses are placed at opposite ends of the chambers; and it is immaterial whether both corner brick shapesof the same course are placed in the same end of the chamber, or diagonally opposite one another. I,

The variation of the cross section which must'be made from course to course during construction, is efiected very simply by first laying the corner brick shape with the proper offset in both longitudinal and transverse directions from the next course be1ow;'-;the rest of the brick in the side and end walls will then conformto the given variation. It is of course possible to. vary inthe same way only one-dimension, the longitudinal or the transverse.

The bonding in alternate courses of the side wall into the ends of the chamber can also be effected by having the ends'of' the chamber mortise into special recesses in the side walls, the extreme bricks of the end walls being manufactured, or trimmed on the job, so as to form the truncated corners of the chamber, while the recess in the side wall is formed throughout the height of the chamber, of a single shape of brick. The construction of the chambers is done, as regards the placing of these end wall corner bricks, course by course in the same manner as already described for the case of corner shape brick. The recessed side wall brick together with the end wall corner brick are shifted or offset for each change in cross section of chamber, just as the corner shapes discussed above- 'The diagonal arrangement of corner bonds can also be used in connection with this type of design.

. By this method it is thus possible to build rectangular gasification chambers with truncated interior angles and tapered walls, of any cross sectional and vertical dimensions whatsoever, out of a single model of brick shape in connection with brick of standard form, with bonding of end and side walls into one another. The number of brick shapes required is thus reduced to two cor ner shapes differing only in the location of the, tongue and groove, one wall shape, and one shape forming the truncated corners of the front wall masonry. lVhere the corner shapes are placed opposite one another, only one model of corner brick is necessary. If the typeof construction is that in which the end walls are bonded into recesses in the side walls, the corner shape is divided, in a certain sense, into a side wallbrick and an end wall corner brick, but in this case even for the non-diagonal arrangement only i one model of shape brick is required. This extremely reduced number of brick models can thus be kept in stock and used for all such chamber construction, so that new jobs and repairs can be executed in minimumtime.

An example of the application of the invention is illustrated by the accompanying drawings. Fig. 1 .shows a longitudinal vertical section through a vertical chamber built in a'ccordancewith the invention; Figs. 2 and 3 show horizontal sections through two courses, Fig. 2 being a section on line AB and Fig. 3 a section on line CD of Fig. 1.

Fig. 4 shows in cross section the diagonal arrangement of corner shapes. Fig. 5 shows in cross section the type of construction in which the ends of the chamber bond into recesses in the side wall. Fig. 6 is a de tail View of corner shape 1. Fig. 7 is a detail view of wall shape 3. I Fig. 8 isa detail View of brick shape 4. Fig.9 is a detail view of side wall shape 5 and end wall corner shape 6 showing the shapes separated but in 1 and 2, wall shape 3, shape 4 forming the truncated corner of the front wall masonary, and the front wall masonary itself. During construction corner shapes 1 and 2, as can be seen from Fig. 2, are laid first. By these two corner shapes the truncated corner of the chamber is formed, and also the bonding of the side wall into the end of the chamber is secured. On these corner shapes follow wall shapes 3 in the direction of the side wall, whose further end runs into special chases in the front wall masonry. To assure gas-tightness between chamber and fines and to fill up the chase left for the side wall, an additional wall shape 3 is placed beyond the rear end of the corner shape. According to the length of the chamber, the opposite side of the front wall masonry is laid up independently ofthe wall shapes 3 which form the boundaries of the chamber end opposite the corner shapes 1 and 2, and the truncated corners are formed by brick shapes 4, which are delivered ready made or can be trimmed to shape on the job. Since the two longitudinal walls of the chamber are not directly tied together by brick shapes,

the choice of the transverse axis is not re- 1 stricted. The space left between the legs of corner shapes 1 and 2 and the two bricks 4 is filled by the front wall masonry, which is built of standard brick. To obtain a good bonding of the masonry, and to secure stability of construction by tying the longitudinal walls into the chamber ends, corner shapes 1 and 2 and also bricks'4 are, as can be seen from Fig. 3, interchanged as construction proceeds. The arrangement of the rest of the masonry, corresponding to the interchange of these shapes, remains the same. I

In order to secure the proper inclination or batter of one or both pairs of chamber walls, corner shapes 1 and 2 are slightly offset from those of the course below, and all other shapes as well as the bounding masonry will conform to the given variation of dimensions. v v

If corner shapes 1 and 2, as shown in Fig. 4, are placed diagonally opposite one another,

the whole job can be built with only one instead of both of the shapes 1 and 2.

The construction of the chamber proceeds in the same manner if, as shown in Fig. 5, the end walls mortise into recesses in the side walls. Insteadof corner shapes 1 and 2, side wall shape 5, made with a recess, and end wall corner shape 6, are first laid, after which side wall shapes 3 are laid to fit as shown. In this case side wall shapes 5 and end wall corner shapes 6 can be all alike (without distinction of right and left), even with the non-diagonal arrangement. In all other respects the construction is the same,

as when corner shapes 1 and 2are used.

With this method of construction itis thus not only possible to build gasification chambers of rectangular cross section with truncated interior angles and tapered walls, rapidly and safely with the use of only a very small number of unchanging models of brick shapes, but the construction is also easily supervised and meets all requirements of stability and durability in operation.
